Background: Parathyroid Cyst (PC) is a rare and unsuspected disease. There are more than 300 cases reported in the international literature. We present a case with an extensive literature review. Methods: We are reporting a patient with a PC that is a 65-years-old female with a neck ultrasound showing well-defined cystic lesion measuring 25 mm × 10 mm × 12 mm in size. She had a past medical history of non-toxic multinodular goiter. She was asymptomatic, with normal laboratory results. The patient had no evidence of parathyroid dysfunction or compressive symptoms. A Fine Needle Aspiration Biopsy (FNAB) was performed, which confirmed the diagnosis of a PC. A left inferior parathyroidectomy was programmed successfully performed through a minimal invasive focused incision and uneventful recovery. Histopathology was confirmed with unilocular cyst with an intact capsule. Conclusion: PC is extremely rare and difficult to diagnose due to their nonspecific presentation and imaging features.
